MACHINE FOR MAKING LAMP WRAPPERS AND THE LIKE.

Application filed February 3, 1922. Serial No. 533,807.

To all whom it may conoem:

Be it known that I, BERG HEINRICHS, a citizen of the United States, and a resident of Chicago, in the county of Cook and State 6 of Illinois, have invented certain new and useful Improvements in Machines for Making Lamp Wrappers and the like, of which the following is a full, clear, and exact description.

The invention relates to machines for making lamp wrappers and the like.

One object of the invention is to provide a machine for formin lamp wrappers composed of a corrugated strip of'straw board 1 and a previously printed sheet of suitable paper projecting from the margins of the corrugated strip and adapted to be twisted and folded into the ends of the wrapper to hold the lamp therein. Another object of the invention is to provide improved means for cutting the finished web at the proper point so that the printed matter thereon will be correctly disposed on the wrapper.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figs. 1 and 2 are views from op osite sides.

1g. 3 is an end elevation. ig. 4 is a vertical longitudinal sectiori. Fig. 5 is a perspective of the finished wrapper. Fig. 6 is a section of the adjusting mechanism for the cutter. Fig. 7 is a section taken on line 77 of Fig. 6.

The wrapper produced 'by the machine consists of a corrugated stri 8 adapted to. extend around a lamp or other article and a fly sheet 9 secured to the crowns of the corrugations on one side of the strip 8 and formin marginal extensions 10 which are 'adapte to be twisted to hold the wrapper around the article and to be tucked in with the article if desired. In practice, the fly sheet 9 is usually printed to indicate the contents and for advertising purposes. The machine is adapted to form the wrappers from continuous webs of stock for the strips 8 and 9.

' The several mechanisms. of the machine are supported by a frame formed of sides 11 which are suitably cross-connected to form a rigid structure. Brackets 12 support a roll of straw board 13 for forming the strips 8 of the wrappers. Brackets 14 fixed to frame 11 support a roll of paper -18, drives the corrugating 15 adapted to form fly sheets 9 of the writ pers. The web 13 passes from its supp y roll around guide-rollers 16 and 17 to a pair of rolls 18 and 19 which are provided with interfitting corrugated peripheries. Each of the rolls 18 and. 19 is heated by steam supplied through pipes 20. Roll 19 is supported in bearings 22 held in the frame 11 and" roll 18 is supported in bearin s 23 which are slidably mounted in the ame and pressed towards the roll 19 to cause the roll 18 to apply pressure to the web 13 as it passes between the coacting corrugated rolls. A paste roll 24 is adapted to apply paste from a bath 25 to the crowns of the corrugations of theweb 13 while it is on the roll 19. Adjustable guides 26 and 27 are provided to hold the corrugated web on the roll 19. The web 15 passes from its supply roll around a guide-roll 28 to a pressure roll 29 which is adapted to press the webs 15 and 13 together while the are passing between rolls 19 and 29. Roli by steam supplied through a pipe 30, is mounted in bearings 31 which are slidably held inframe 11 and is subjected to pressure of springs 32 to force the roll 29 to-- wards the upper portion of the corrugated roll '19. As the webs 13 and 15 pass throu h rolls 19 and 29, they will be ali ed. T .13 combined web passes to a .pair 0 feed rolls 33 and 34 which are adapted to force the 29 is heated.

web to a cutter comprising a stationary the 'rame 11. A pinion 62 fixed to said shaft and meshing with a gear 63 on roll roll 19. .A gear 64 on roll 29 meshes wit gear 63 to drive said roll. A shaft 65 is drlven by a pinion 65 which meshes with gear 63. A sprocketwheel 65 on shaft 65 drives a chain 66 which drives as rocket 67 which drives a gear 68 which mes es with a gear 69 on feed-roll 34. A gear 70 on feed-roll 33 meshes with gear .69so that both of said feed-rolls will be synchronously driven. A sprocket-wheel71 is secured to rotate with sprocket 67, and the chain 7 2 drives a sprocket-wheel 73 from sprocket 71. A variable driving mechanism 74 is driven by the sprocket 73. This mechanism may be such as is usually known as a belt, as Well understood in the art.

necessary Reeves variable speed transmission which comprises ashaft 75 driven by sprocket 73 and a shaft 76 driven by the variablev s g aleied 1e driven shaft 76 has secured thereto a sprocket 77 which drives a chain 78 which passes around a s rocket 43 for driving the rotatable cutter 3 By adjustment of the variable speed mechanism 74, the speed or number of revolutions of the cutter 37 relatively to the feed of the web may be varied to form wrappers of different lengths. The glueing roll 24 is driven by a gear 24 which meshes with a gear 24 which rotates with the corrugating roll 19.

Inthe manufacture of these wrappers, it is desirable to have the printed matter correctly positioned on each wrapper, and for this purpose, mechanism is provided for timinthe'position of the cutter 37 so that it wi j? cut-"the combined web on the proper lines. Since this adjustment is frequently in the manufacture of these wrappers, it is also desirable to have adjusting means which can be operated with facility and without disconnecting the driving mechanism for the cutter or while the machine. is in operation. For this purpose, the shaft 39 is driven through the sprocket 43 which is loose on one end of shaft 39, is held thereon by a collar 44 and is secured to an internally toothed ring-gear 45. The teeth of gear 45 mesh with idlers 46 which are loose on studs 47 and mesh with a gear 48 which is keyed to the shaft 39. The studs 47 on the idlers 46 are mounted in a carrier 49 which is mounted to rotate around one ofthe bearings 40 and is provided with external teeth which are engaged by an adjusting pinion 50 which is fixed to a shaft 51 which is mounted in the frame, provided with a crank 52 whereby it may be manually turned to operate the adjusting mechanism and is adapted to be locked by a set screw 53. In operation, the sprocket 43 drives the ringgear 45 which rotates the idlers 46 to drive the gear-wheel 48' which is fixed on cuttershaft 39. Whenever timing of the cutter 37 relatively to the forming mechanism is necessary, the crank 52 will be turned to rotate pinion 50, carrier 49 and studs 47, imparting a planetary movement to the pinions'46 which will shift the gear 48 and r0:

'tate shaft 39 while the'ring-gear 45 and sprocket 43 remain stationary. This adustment may be made while the sprocket '43 .is being driven, because the movement of carrier 49 maybe then effected and will cause the necessa relative movement between gear 48-an the ring-gear 45 to effect the desired ad'ustment. As a result, the cutter 37 may e quickly timed. This meaoec adjustment is also used to time the cutter 37'v when the speed of the sprocket wheel 43 is changed to cut wrappers of different lengths.

The invention exemplifies a machine for operation or at rest to cause the web to be y out between the printed portions of the web.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.'

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:
